As usual, it was full of some of the best puzzle ideas in the world. Moreso than usual, in fact: it was epic by the Hunt’s own standards – the largest hunt ever produced, with 150 puzzles, most roughly half again the size, complexity, and difficulty of traditional Mystery Hunt puzzles. The variety of clever ideas in both individual puzzles and meta structure was impressive, alternating between rewarding and confusing. Some puzzles realized a beautiful concept that other teams (including Codex and Metaphys) had considered when writing previous hunts, but not pulled off. Some were built around a conceptual encoding whose very idea was beautiful — an infinite cryptogram, a fractal word-search, purely group-theoretical encodings, a puzzle tracing out Feynman diagrams, a regular-expression ‘crossword‘, a Chaotic language-evolution analysis, a real-life Enigma puzzle complete with figuring out how to properly construct your own machine… a safe door you had to get around by climbing through ducts… a life-size Laser Maze worthy of its own Zone. The heist team we recruited was brought to life in character, including Indy, Maxwell Smart, and Ernő Rubik. The parts that fell together were ridiculously awesome.

And there was a focused effort to make an longer hunt, targeted at large teams that could parallelize most puzzles as soon as they appeared. Some puzzles were designed to be the largest puzzle of that type you’d ever done: a 2000-piece non-interlocking [jigsaw] puzzle, a 50×50 paint-by-number, a 26×26 cryptic, a music-identification puzzle with 263 clips. All of the methods used in the past decade to make hunts more elaborate – novel puzzle types and meta concepts, increased puzzle size, adding additional extraction steps – were tried, sometimes in a single puzzle.

The organizers got a bit carried away with all of this. Unintentional pitfalls that make hunts run long showed up as well: some unpolished puzzles with confusing or unclued extractions, metas with many blind alleys, events that produced hard-to-decipher clues, single hard puzzles serving as a bottleneck to a round.

Common refrains from puzzle reviews: “If it had been two or three steps shorter, I would have counted it among the best Hunt puzzles I’ve seen.” “We got stuck on the third aha, and further answers didn’t help us much.”

In all, the Hunt would have run into Tuesday without intervention, twice as long as its authors intended. By 2am Sunday, HQ started to send out hints. By Sunday night, serious hinting and free answers began. Somehow Sages managed to do all of this in a way that felt fair to all competing teams.

Codex was at half-mast this year and not fully engaged, but we still had a good 80 active participants, including many talented first-timers. And, most important, we all had a great time and much-needed break from the far less polished puzzles of life itself. Thanks to all who joined in this Hunt, and especially to those who ran two additional events – the Intro to Hunting session on Thursday night (designed by Mikalye and run by cScott “meteoric” Ananian, Andrew “the answer” Lin, and Molly Millions) and our commemoration for Aaron on Friday.
